“…Given the importance of the fisheries sector to nutrition, food security, livelihoods, and poverty alleviation-especially in developing countries [1][2][3], it is imperative that IUU fishing is addressed as it could lead to resource degradation and fisheries unsustainability. As a response to IUU problems, the Fisheries and Agriculture Organization of the United Nations (FAO) drafted an International Plan of Action, with a set of principles guiding member states in their national-level effort to prevent, deter, and eliminate IUU fishing (IPOA-IUU) [4].…”

Illegal, unreported, and unregulated (IUU) fishing is a major concern in fisheries management around the world. Several measures have been taken to address the problem. In Lake Victoria, the alleviation of IUU fishing is implemented through the Regional Plan of Action (RPOA-IUU), which restricts use of certain fishing gear, as well as prohibits fishing in closed areas and during closed seasons. Despite the long-term efforts to monitor and control what goes on in the fisheries, IUU fishing has persisted in Lake Victoria. Inspired by interactive governance theory, this paper argues that the persistence of IUU fishing could be due to different images that stakeholders have about the situation, rather than the lack of management competency. Through structured interviews with 150 fisheries stakeholders on Ijinga Island in the southeastern part of Lake Victoria, Tanzania, using paired comparison questionnaires, the study elicits stakeholders' perspective about the severity of different locally-pertinent fishing-related activities. The results show that while fisheries stakeholder groups agree on their judgments about certain fishing gears, some differences are also apparent. For instance, fisheries managers and scientists do not always agree with fishing people about what activities cause the most damage to fisheries resources and ecosystem. Further, they tend to consider some IUU fishing-related activities less damaging than some non-IUU fishing. Such disparity creates governability challenges, pointing to the need to revisit relevant regulatory measures and to make them consistent with the knowledge and judgments of all stakeholders. Based on these findings, we discuss governing interventions that may contribute to addressing IUU fishing in Lake Victoria and elsewhere.

Summary:Artisanal fisheries are often overlooked by fisheries management agencies despite their great importance for food security and livelihoods. The assessment and management of those fisheries is often rare, especially in developing countries. In Mozambique, a probability-based survey for the monitoring of the small-scale fisheries has been conducted in several coastal provinces since the late 1990's. Here we used the Mozambican on-shore data collection programme to illustrate both the difficulties and possibilities of estimating trends in catch per unit of effort (CPUE in kg day -1 ) for stocks when data is limited in both quantity and quality, as is often the case for artisanal fisheries. Data on catch and effort collected between 1998 and 2009 from four regions along the Mozambican coast and two different gears were used to assess the status of two species (Hilsa kelee and Thryssa vitrirostris) exploited by the artisanal fisheries. The results showed that standardized CPUE have declined for some of the regions and gears analysed, whereas for others the trend has been stable or has even increased during the last 12 years. However, when CPUE is scaled for the increase in net length, most of the times series show a declining trend.Keywords: artisanal fisheries; Mozambique; CPUE.Tendencias de la CPUE de Hilsa kelee y Thryssa vitrirostris explotadas por la pesquería artesanal en Mozambique a partir del muestreo de las capturas en puerto Resumen: La pesca artesanal casi nunca se tiene en cuenta por las agencias de gestión de la pesca a pesar de su gran importancia para la seguridad alimentaria y medios de vida. La evaluación y la gestión de estas pesquerías no es muy frecuente, especialmente en los países en desarrollo. Desde finales de 1990 en varias provincias de la costa de Mozambique se llevó a cabo un seguimiento de las pesquerías artesanales basado en un muestreo probabilístico. Aquí hemos utilizado el programa de obtención de datos en el puerto de Mozambique para ilustrar las dificultades y posibilidades de la estimación de las tendencias de la captura por unidad de esfuerzo (CPUE en kg día -1 ) para los stocks cuando los datos son limitados en cantidad y en calidad, como sucede a menudo en el caso de la pesca artesanal. Se utilizaron datos de captura y esfuerzo recogidos entre 1998 y 2009, en cuatro regiones a lo largo de la costa de Mozambique y con dos artes de pesca distintos, para evaluar el estado de las dos especies (Hilsa kelee y Thryssa vitrirostris) explotadas por las pesquerías artesanales. Los resultados mostraron que la CPUE estandarizada se ha reducido para algunas de las regiones y artes analizados, mientras que para otros la tendencia se ha mantenido estable o incluso ha aumentado durante los últimos 12 años. Sin embargo, cuando se escala la CPUE para el aumento de la longitud de la red, la mayor parte de la serie de tiempos muestra una tendencia a la baja.

Small-scale fishers use a wide range of gear and fishing techniques, catching large quantities of fish (Salas et al., 2007). The operation of the small-scale fishing fleet is constrained by environmental characteristics and the seasonal behaviour of the exploited resources.In Florianopolis, various types of fishing gear are found, with a predominance of gillnets (anchorage, driftnet, etc.), as well as zangarilho to catch squids and beach seine IntroductionFishing activity may be considered as the combination of different interacting components, including man, natural resources and management systems, influenced by internal and external factors. As such, fishing is composed of a group of interrelated activities, including capture, fish processing, the market and the consumer's demand for fish, operating on certain socioeconomic and political contexts (Salas and Gaertner, 2004 AbstractThe objective of this paper is to describe the main characteristics of small-scale marine fisheries in the municipal district of Florianópolis (SC), the capital city of the state of Santa Catarina. We give information about the most captured species, the fishing fleet and fishing gear used. The dynamics of the activity is described, considering the kind of operation of the boats, alongside post-capture procedures. The analyses were accomplished in two types of fishing communities: the one composed of fishers that fish in bays (North and South) and those who fish in the open sea. Numeric differences were observed among these two fishing areas, indicating the existence of two different fleets operating in the area. Differences between the two fishing areas were detected, considering the species caught, the harvest time and the fishing gear used. The open sea fishers have boats with dimensions, engine power, number of crew and fuel consumption numerically higher than those working in bays, indicating the existence of two distinct fleets operating in the region.Keywords: marine small-scale fisheries, fishing dynamics, fishing gear, harvest season, Florianópolis. Pescarias marinhas de pequena escala no município de Florianópolis, Santa Catarina, Brasil ResumoEste trabalho teve como objetivo caracterizar a pesca de pequena escala no município de Florianópolis (SC). São apresentadas informações sobre as principais espécies capturadas, sobre a frota e artes de pesca utilizadas, sobre a dinâmica da atividade, considerando a forma de operação das unidades produtivas, e sobre os procedimentos pós-captura adotados. As análises foram realizadas em dois tipos de comunidades pesqueiras: as compostas por pescadores que atuam em baías e aquelas cujos integrantes pescam em mar aberto. Foram detectadas diferenças entre as duas áreas de pesca considerando as espécies capturadas, as épocas de captura e as artes de pesca utilizadas. Os pescadores de mar aberto possuem embarcações com dimensões, potência dos motores, número de tripulantes e consumo de combustível numericamente superiores aos que atuam nas baías, indicando a existência de duas frotas dist...
